' 1 Claim. or. 15-29 This invention relates to a dairy utensil and more particularly to an improved machine for washing udders. Heretofore udder washing machines have been proposed .utilizing for. the most part a spray of water within'areceptacle in which the udders are disposed. Such machines have not proven totally effective in that particles of dirt or the like were oftentimes not removed simply by the water spray.

It is an object of the present invention to provide a washing machine for udders which will thoroughly cleanse the udders.

It is a further object of the present invention to provide a washing machine for udders which is light, compact and portable.

It is still a further object of the present invention to provide a washing machine for udders which, while effectively cleaning the udders, will not injure the same.

It is still a further object of the present invention to provide a washing machine for udders which is durable and has longevity despite extended use.

Still another object of the present invention is to provide a washing machine for udders having all the desired advantages which is nevertheless inexpensive to manufacture and easy to produce.

Other objects and advantages are set forth in greater detail in the accompanying specification taken in conjunction with the accompanying drawings, in which:

Fig. 1 is a side elevation view partially in section of the machine for washing udders of the present invention;

Fig. 2 is a top view partially in section of the machine of the present invention;

Fig. 3 is an enlarged view of the means for cleaning udders according to the'present invention; in partially disassembled relation and Fig. 4 is an enlarged axial sectional view of the water nozzle of the machine of the present invention with the retaining ring removed.

Referring particularly to the drawings, there is shown an apparatus for washing udders of cows. The machine consists of power means in the form of an electric motor contained within the housing 11. The electric motor is of the usual conventional fractional horsepower type. A handle 12 is provided to the rear of the housing 11 for the electric motor. The handle 12 has a hollow bore accommodating a wire 13, the end of which (not shown) is to be connected to an outlet for supplying a source of electrical energy. A switch 14 is located on the handle 12 for switching the electric motor on and oif as desired. Another handle 15 is provided, as shown, above the housing 11 for the purposes hereinafter set forth. Clips 16 are provided at the base of the housing. Another clip 17 engages the electric cord 13. A water pipe 18 passes through the clips 16 and 17 which maintain the water pipe in position. One end of the water pipe, not shown, is secured to suitable water supply means. A water valve 19 is disposed to the rear of the housing for controlling the flow of water through the pipe 18 as desired.

motor causes the shaft to rotate.

'According to the present invention, secured to the motor at the forward portion thereof is a reducing box 20 containing reduction gears for the purposes hereinafter set forth. A rotatable shaft 22 is provided through the reducing box 20 and engaging the reduction gears. The forward end of the shaft 22 has a bevel gear '23 which, according to the present invention, engages a gear 24, as shown. Secured to the gear 24 and rotatable therewith is a disk 25 made of any suitable material. The disk is provided with a central opening 26 adapted to receive a nozzle 27. One end of the removable nozzle is provided with perforations 28. The other end of the nozzle is connected by a coupling 29 to the end 30 of the water pipe 18. i I

To maintain the nozzle 27. in position in the disk 25 a snap ring 31 is secured around the shaft in the groove 31a below the perforations 28. The snap n'ng prevents the hollow shaft from inadvertently passing through the aperture 26 in the disk 25. Brushes 32 are'secured to the upper side of the .disk 25 at predetermined spaced intervals.

The operation of the apparatus for washing udders of the present invention is as follows: The wire 13 is connected to a suitable source of electrical supply. The water pipe 18 is connected to a suitable source of water supply. The switch 14 is thrown permitting energization of the electric motor rotating the shaft 22. The electric The rotation of the shaft, according to the present invention, is decreased for the purposes hereinafter set forth by means of the reducing gears within the reduction box 20. The bevel gear 23 at the forward end of the shaft causes rotation of the disk 25 carrying the brushes 32 around the nozzle 27. The water valve 19 is opened permitting the flow of water through the pipe 18 and nozzle 27 and out of the perforations 28. The apparatus 10 is supported by the handles 12 and 15, and brought into position wherein the tops of the brushes 32 engage the cows udders. The lightness and compactness of the apparatus permits it to be portably manipulated as described. The rotation of the brushes 32 causes them to clean the cows udders removing dirt and like matter therefrom in a brushing action. The water is ejected from the perforated nozzle 28 onto the brushes keeping them wet whenever desired.

According to the present invention, injury to the cows udders is prevented even with the use of relatively hard bristle brushes which are used for effective cleaning, by means of the gearing arrangement. The disk 25 carrying the brushes 32 turns at a desired speed so that a gentle cleansing action is applied to the udder of the cow to clean the same without injury to the udders.

The disk and brushes may be removed for cleansing simply by disconnecting the clip 31 from the nozzle 27 whereby the nozzle may be removed through the opening 26 and the entire brush unit may be cleaned apart from the remainder of the apparatus for an effective cleansing between uses.

According to the present inevntion all moving parts of the apparatus except the bristles are contained within a protective housing as shown.

While the invention has been described in some detail, it will be understood that variations and modifications may be made without departing from the spirit thereof or the scope of the appended claim.

I claim:

A brush for cleansing the udders of cows, said brush comprising a housing, said housing having a bottom wall and a peripheral side wall integral with said bottom wall and extending upwardly from said bottom wall, said bottom wall and said side wall defining an upwardly opening recess having an upper peripheral edge, means forming a central aperture in said bottom wall, a nozzle positioned in and closing said aperture and extending vertically upwardly above said upper edge, said nozzle having a cylindrical periphery, a brush disk, said disk having a central aperture, said nozzleextending through said aperture with said disk being rotatably journaled on said nozzle, a ring gear depending peripherally beneath said disk, asecond gear in mesh with said ring gear, said' disk having an upper surface substantially flush with said upper edge, said upper surface extending from the peripheral edge of said disk radially inwardly of said disk to substantially said central aperture, said disk having an annular recess in its said upper surface axially aligned with the aperture, the latter recess having a lower wall extending radially of said aperture, said nozzle having a peripheral groove adjacent the latter wall, a removable retaining member seated in said groove and bearing against the latter wall and releasably and rotatably retaining said disk onsaid nozzle, brushes secured to said disk radially outwardly of the latter recess and projecting vertically above the latter recess, means forming orifices in said nozzleabove said disk but beneath the tops ,4 of said brushes, said orifices being adapted to direct fluid spray outwardly and upwardly toward the tops of said brushes, means removably connecting said nozzle to said housing, means connecting said nozzle to a source of fluid supply, said disks, ring and brushes being readily removable from said recess to expose the interior thereof for cleaning purposes, means for rotating said second gear.
